Blackboard.
Part 1: Questions.
Step 1:
a. Which command displays the statistics for all interfaces configured on a router? Show Interface
b. Which command displays the information about the Serial 0/0/0 interface only? Show Interface Serial
0/0/0
c. 1) What is the IP address configured on R1? 209.165.200.225
c. 2) What is the bandwidth on the Serial 0/0/0 interface? 1544 Kbit
d. 1) What is the IP address on R1? There is no Ip address on R1 Gig 0/0
d. 2) What is the MAC address of the GigabitEthernet 0/0 interface? 000d.bd6c.7d01
d. 3) What is the bandwidth on the GigabitEthernet 0/0 interface? 1000000 Kbit
Step 2. Questions.
a. Which command displays a brief summary of the current interfaces, statuses, and IP addresses
assigned to them? Show Ip interface brief
b. 1) How many serial interfaces are there on R1 and R2? R1 has 2 Serial Interfaces and R2 has 2 Serial
Interfaces
b. 2) How many Ethernet interfaces are there on R1 and R2? R1 has 6 Ethernet interfaces and R2 has 2
Ethernet interfaces
b. 3) Are all the Ethernet interfaces on R1 the same? If no, explain the difference(s). No there are two
different Ethernet interfaces on R1. R1 has a 4 FastEthernet and 2 GigabitEthernet ports on it. The
difference is that GigabitEthernet has more bandwidth than the FastEthernet port.
Step 3: Display the routing table on R1.
a. What command displays the content of the routing table?
Show Ip Route
b. 1) How many connected routes are there (uses the C code)? 1
b. 2) Which route is listed? 209.165.200.224/30 is directly connected, Serial0/0/0
b. 3) How does a router handle a packet destined for a network that is not listed in the routing table?
The packet will be dropped if the destination network is not in the routing table.
Part 2 Step 3
a. What command did you use? show ip interface brief
Part 3 Step 1
a. 1) How many interfaces on R1 and R2 are configured with IP addresses and in the “up” and “up” state?
Both routers have 3 interfaces with Ip address and in the up and up state.
a. 2) What part of the interface configuration is NOT displayed in the command output?
The Subnet Mask
a. 3) What commands can you use to verify this part of the configuration?
Show interface / show run
b. 1) How many connected routes (uses the C code) do you see on each router?
Both routers have 3 connected routes.
b. 2) How many EIGRP routes (uses the D code) do you see on each router? There seems to be an issue
with packet tracer or my configuration. Both routers should only have 2 EIGRP routes however, R2 has 4
EIGRP routes. It looks like R2 is showing it’s 2 directly connected LANS as dynamically learned. If I’m not
mistaken the only EIGRP routes that should be in a routing table are the Networks that are learned from
other routers. I reset the LAB and started it over and I still got the same result.
b. 3) If the router knows all the routes in the network, then the number of connected routes and
dynamically learned routes (EIGRP) should equal the total number of LANs and WANs. How many LANs
and WANs are in the topology? There are 4 LANs and 1 WAN
b. 4) Does this number match the number of C and D routes shown in the routing table? NO but it should
have.
